SWAB-HOLDER.

Specification of Letters Patent.

Patented Mar. *7, 1911.

Application filed June 1Q, 1910. Serial No. 5663.65.

To all whom it may concern:

Be it known that I, BERNHARDT WV. STEIN- mm a citizen of the United States, residing at San Antonio, in the county of BeXar and State of Texas, have invented a new and useful Swab-Holder, of which the following is a specification.

This invention relates to improvements in swab holders designed for use in connection with pump or other piston rods for the lubrication thereof; and it is the object of the invention to provide a holder of this kind which can be readily applied to the rod, and which is so constructed that waste may be used to pack the same, and also to provide a holder which can be repacked without removal from the rod.

lVith these and other objects in view, which will appear when the nature of the invention is better understood, the same consists in a novel construction and arrangement of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a vertical section showing the application of the invention. Fig. 2 is an elevation showing the holder closed. Fig. 3 is a perspective view of the holder in open position.

In the drawing, the invention is shown applied to a piston rod 5 passing through a stufiing box 6 closed by a gland nut 7. It is to be understood however, that the holder may be applied to any other form of stuff; ing box and closure therefor, and that it is not limited to the particular form shown, and furthermore, it may also be applied to shafts, valve rods, or any other rods requiring lubrication.

The holder comprises a cylinder casing which is in two hinged sections, so that it may be placed in position around the rod. The two sections of the cylindrical wall of the casing are indicated at 8, they being connected by a hinge joint formed by hinge knuckles 9 on the sections, and a pin 10passing through said knuckles. The free ends of the sections 8 are formed with cars 11 which are in alinement when the holder is closed, and a pin 12, passing through said ears, locks the holder in closed position.

The holder is closed at its ends, there being central openings in the end walls, through which openings the rod 5 passes. The end walls are also in sections, the two sections at one end being indicated at '18.

These two end wall sections are rigidly secured, respectively, to the sections 8, and swing therewith. The other two end wall sections are indicated at 14, they being mounted to swing independently of the sections 8 by being pivotally connected thereto by means of the pin 10, the latter passing through perforated ears 15 on said sections 14. The free ends of the sections '14 are also formed with perforated ears 16 which are in alinement with the ears 11 when the holder is closed, and through which is adapted to be passed the pin 12, whereby said sections are locked in closed position with the other sections of the holder. To the sections 8, on the outside thereof, are secured fingers 17 which project from one end thereof, and have inturned terminals 18. In the end wall sections 14 are small openings 1.9 to permit the introduction of oil into the holder when it is in position on the rod. The sections 14: also have a marginal flange 20 fitting the sections 8 exteriorly. v

The holder' herein described is applied to the rod by opening it as shown in Fig. 3, in which position it can be readily placed around the rod. The sections are then closed and locked by the pin 12. The holder is so positioned on the rod that the fingers 17 eX- tend along the outer surface of the gland nut 7, the inturned terminals 18 extending behind the rear end thereof, whereby the holder is held stationary, and prevented from traveling with the rod. The end wall sections 14 are at the outer end of theholder, so that the openingslt) are readily accessible if it is desired to introduce oil into the holder.

It will be understood that the holder is to be filled with waste or other absorbent material which is kept soaked with oil. If it is desired to renew the packing, it can be 'read ily done without removing the holder from the rod, by swinging the end sections 14 open.

The holder herein described does away with the use of a lamp wick, and waste can be used to pack the same. The oil applied to the packing will remain in the holder and not run out of the same. When once applied to the rod, it may remain there permanently,

renewal of the packing being readily effected as already described, without removing the holder, and the packing can: also be kept soaked with oil without the necessity of removing the holder. The sections 14: have a marginal bead 21 to provide a neat finish and prevent the oil from running over where the holder is applied to an upright rod, and

the inner edges of the sections 13 have a head 22 for trapping a little of the oil within the casing when the latter stands horizontal.

hat is claimed is:

A swab holder comprising a casing made ing openings for the admission of oil; com- 15 hined with fingers secured to said casing sections on lines parallel with its axis and projecting away from said wall sections and having their outer ends turned toward each other.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

BERT STEINERT.
